I Fig. 9 is similar to Fig. '7 but shows the type of boxblank which isdisclosed in Fig. 8. 1

One type of wirebound box blank is shown in Fig. 1 consisting of foursections of cleats I and 3 side sheets 2 and 3 connected together infoldable relationship by flexible binders (preferably 5 wires) 4 stapledto the sheets and cleats. In the blank shown in Fig. l, the sheet 3 ofeach section overlaps the sheet 2,"as shown. This overlappingrelationship of the sheets is desirable for the shipment of certaincommodities.

Fig. 2 discloses a different type of wirebound box blank which may bemade on the machine. It consists of cleats l and an integral sheet ofside material 5 preferably of fiberboard or the like which may be bentat potential box corners 55 when the blank is folded into box form. Un-

derlying the sheet 5 at each potential box corner is a strip of bendablematerial (preferably fiberboard) 6. The strips 6 are incorporated tostrengthen the completed box at and adajcent the corner edges. stapledto the sheet 5, the strips 6, and the cleats l, are flexible binders(preferably wires) 1.

Referring to Fig. 3, the cleats and sheets for. a box blank arepositioned on endless cpnveyor chains 8 which carry the material beneath10 stapling mechanism 9 which staples the box parts together and thebinding wires thereto. In said figure, the materials are fe to h plmechanism 9 in the direction indicated by the arrow. As the materialsapproach the stapling mechanism 9 they pass under presser bars it] whichpress the box parts firmly into position on the conveyor Chains during astapling operation.

Referring to Fig. 5, each conveyor chain is 1 channel-shaped to receivethe cleats l. The cleats I are positioned endwise by fins ll extendingfrom blocks l2 adjustably secured to a flange 13 of the chains 8. Therear edge of overlapping sheet 3 is positioned by fins 14 carried byblocks E2. The ends of the side sheets are held against lateral movementby outer flanges 15 of the chains 8.

Because the sheets o side material sometimes warp, the fins l4 extendabove the true suriace level of the sheet to insure engagement with therear edge of the sheet regardless of its warped condition. Similarupwardly extending fins or fingers must be proyided to contact andposition the rear edge of the under er overlapped sheet 2. Such means,however, necessarily lies beneath" upper sheet 3 and therefore holds itin the raised position shown in Fig. 6 and out of contact with undersheet 2, Durin the feed of the box parts to the stapling mechanism 9 theupper sheet 3 need not contact with the lower sheet 2, but when the twosheets are stapled together itis necessary for them to belt; con.-

tact with each other. Therefore, provision is made tolower thepositioning fin or finger for the under sheet 2 during the time thesheets 2 and 3 are being stapled together.

The device for accomplishing this result is best shown in Fig. 4. Itconsists of a block 16 which may be adjustably secured to a flange ll ofchains 8 by means of set screws I8. The block l6 carries an upwardlyextending positioning finger H] which is mounted to slide vertically inthe block l6.

As best shown in Fig. 6, finger I9 is normally sheet 2.

The pressure for lowering the finger l9 may be applied by the presserbars as the materials are fed beneath it, or by the thrust of thestapling mechanism when it drives a staple through the upper sheet 3andthe lower sheet 2 and into the cleat I.

Figs. 6 and 7 illustrate the action of the positioning finger 19 whenblanks of the type shown in Fig. 1 are being operated upon, and Figs. 8and 9 illustrate the manner in which the positioning finger l9 operatesto position the strips 6 beneath the sheet when the type of blank shownin Fig. 2 is being operated upon.

The mechanism for feeding the conveyor chains 8 andfor forming anddriving staples need not be described herein, as such mechanisms arewell known, being shown, for example, in pat- (ant to Thompson No.1,738,806 of December 10, 1929, reference to which is hereby made for adetailed description of such mechanisms.

It will be understood that the invention is not to be limited to thespecific embodiment shown for purposes of illustration as it may bevariously embodied without departing from the invention.

' It will also be understoodthat all of the in.- ventive features neednot be used conjointly' as they may be used to advantage in variouscombinations as defined in the sub-joined claims,

' I claim: r

1. In a machine of the character described, the combination of fastenersetting mechanism and means to feed thereto sheets of side materialinoVerIapping relationship including a Vertically slidable positioningfinger to engage the the combination of fastener setting mechanism andmeans to feed thereto sheets of side material in overlappingrelationship includinga vertically slidable positioning finger toengagethe overlapped edge of the under sheet, said finger being longerthan the thickness of said sheet to extend above the true surface levelof said sheet and contact the under side of the overlapping upper sheet,means normally holding the finger in raised position, and means actingthrough pressure on the upper sheet to lower the finger to the-surfacelevel of the under sheet when the upper sheet is being fastened to theunder sheet.

3. In a machine of the character described, the combination of fastenersetting mechanism and means to feed thereto sheets of side material inoverlapping relationship including a vertically slidable positioningfinger to engage the overlapped edge of the under sheet, said fingerbeing longer than the thickness of said sheet to extend above the truesurface level of said sheet and contact the under side of theoverlapping upper sheet, and means yieldingly to hold the finger inraised position whereby pressure on the upper sheet during a fasteningoperation will force the finger down to the surface level of the lowersheet and permit the upper sheet to contact the lower sheet while thetwo sheets are being fastened together.

4. In a machine of the character described, the combination of fastenersetting mechanism and means to feed thereto sheets of side material inoverlapping relationship including a positioning member adapted tounderlie the upper sheet and to engage the rear edge of the lower sheetand to extend above the true surface level of the under sheet, and meansacting through pressure on the upper sheet to lower the positioningmember during a stapling operation.

-5. In a machine of the character described, the combination of fastenersetting mechanism and means to feed thereto sheets of side material insaid member being yieldingly held in raised position whereby pressure onthe'upper sheet during a fastening operation will lower the finger andpermit the upper sheet to contact the lower sheet.

I 6. In a machine of'th character described, the combination of fastenersetting mechanism and means to feed a box part thereto including avertically movable member to engage the rear edge of the box part, meansnormally holding it in raised position, and means acting throughpressure on a box part to lower the member and hold it in loweredposition during a fastener setting operation.

7. In a machine of the characterdescribed, the combination of. fastenersetting mechanism and means to feed a box part thereto including avertically movable member to engage the rear edge of the box part, meansyieldingly holding it in raised position, and means acting throughpressure on .a box part to lower the member and hold it in loweredposition during a fastener setting operation. 8. In a machine of thecharacter described, the combinationof fastener setting mechanism andmeans to feed a box part thereto including a vertically movable memberto engage the rear edge of the box part, means acting through pressureon a box part to lower the member as it approaches the fastener settingmechanism, and means to raise the member after it passes the fastenersetting mechanism.
